Not a show I have seen or ever will see, but this seems to be an excellent review of Girls. If a person tells a story that is true, it will in a way always teach the right moral lesson for those who have eyes to see.

We could also wax indignant about the show’s vulgar language and disgusting incidents. Maybe Girls
goes too far, but for diagnostic purposes good art can exaggerate
what’s revolting. And everything that is genuinely revolting here is
portrayed that way. We see time and again, for example, that there’s
little more degrading than casual sex in the absence of love. When we’re
shown an abortion clinic, or women contracting STDs, or a string of
pathetic hookups, and whiny, brittle, pretend marriages, we see the
stupidity and misery of an abysmally clueless life. The show’s bitter,
intended irony is this: while these girls are so proudly pro-choice,
they lack what it takes to choose well.
